OPERATION
NOTICE: NEVER run pump dry. Running pump dry may
damage seals, causing leakage and flooding. Fill pump
with water before starting motor.
DO NOT run the pump
dry. If the pump is run dry, the mechanical seal will be
damaged and the pump will start leaking. If this occurs,
the damaged seal must be replaced. ALWAYS maintain
proper water level. If the water level falls below the
suction port, the pump will draw air through the suction
port, losing the prime and causing the pump to run dry,
resulting in a damaged seal. Continued operation in this
manner could cause a loss
of pressure, resulting in
damage to the pump case,
impeller and seal and may
cause property damage and
personal injury.
Before
removing trap cover:
1. STOP PUMP before
proceeding.
2. CLOSE GATE VALVES
in suction and discharge
pipes.
3. RELEASE ALL
PRESSURE from pump and
piping system.
If pump is being pressure tested, be sure pressure
has been released before removing trap cover.
Do not block pump suction. To do so with body
may cause severe or fatal injury. Small children
using pool must ALWAYS have close adult supervision.
Fire and burn hazard. Modern motors run
at high temperatures. To reduce the risk of fire, do not
allow leaves, debris, or foreign matter to collect around
the pump motor. To avoid burns when handling the
motor, let it cool for 20 minutes before trying to work on
it. An automatic internal cutoff switch protects the motor
from heat damage during operation.
Priming Pump
Release all pressure from filter, pump, and piping
system; see the filter owner’s manual.
In a flooded suction system (water source higher than
pump), pump will prime itself when suction and
discharge valves are opened.
If pump is not in a flooded suction system, unscrew and
remove trap cover; fill trap and pump with water.
Clean and inspect O-Ring; reinstall on trap groove.
Do not lubricate the trap cover O-Ring. The original
equipment O-Ring contains a permanent internal
lubricant.
NOTICE: If you replace the O-Ring with a non-internally
lubricated O-Ring, you may need to apply a silicone
based lubricant. Replace trap cover on trap; turn
clockwise to tighten cover.
Do not use a wrench, this may damage the trap cover
handle ring which can cause property damage or
personal injury. Tighten trap cover handle ring by hand
only (no wrenches)! See Figure 1, Page 3.
Pump should prime now. Priming time will depend on
vertical length of suction lift and horizontal length of
suction piping.
If pump does not prime, make sure that all valves are
open, suction pipe end is under water, pump is not trying
to lift water more than 10'(3m), and that there are no leaks
in suction pipe. See Troubleshooting Guide, Page 11.
Storage/Winterizing:
NOTICE: Allowing pump to freeze will damage pump
and void warranty!
NOTICE: Do not use anti-freeze solutions (except
propylene glycol) in your pool/spa system. Propylene
glycol, “RV antifreeze”, is non-toxic and will not damage
plastic system components; other anti-freezes are
highly toxic and may damage plastic components in the
system.
Drain all water from pump and piping when expecting
freezing temperatures or when storing pump for a long
time (see instructions below).
Keep motor dry and covered during storage.
To avoid condensation/corrosion problems, do not
cover pump with plastic.
For outdoor/unprotected installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow
ventilation; do not wrap system in plastic.
3. Use a 40% propylene glycol/60% water solution to
protect pump to -50° F (-46° C).
Draining Pump
Purging the system with compressed air
can cause property damage, with risk of severe injury or
death to anyone nearby. Use only a low pressure (below
5 PSI), high volume blower when air purging the pump,
filter, or piping.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.
